C6 Itto Abyss 2.4 12-3-1 Speedrun 21s!!

man i couldn't tell you how many hours i put into this stupid abyss run cuz dealing with crit rng AND ruin grader rng is so bad... this is the best i could manage, and yet i know for sure i can get sub 20 seconds but this is where i end it, i'm not speedrunning this abyss anymore. I wait for 2.5 abyss now
